SPECIFICATION forming pait of Letters Patent No. 571,414, dated November 17, 1896. Application filed October 10, 1895 Serial No. 565,287. (No model.)

To all whom it may concern:

Be it known that LRIOHARD TOEPPER,1ner chant, a citizen of the Kingdom of Prussia, German Empire, and a resident of Naumburg-om the-Saalefinthe Kingdom of Prussia and German Empire have invented certain new and useful Improvements in Type-WVriting Machines, (Oase 13,) of which the following is a specification.

The present invention relates to a typewriting machine having on its type-plate letters, combinations of letters, syllables, words, and other characters which by a singlepressure on a key are impressed upon the paper, a space being moved by the paper-carriage to correspond with the length of the type or character printed.

In the accompanying drawings, Figure 1 represents a plan view of the spacing mechanism, and Fig. 2 an elevation thereof. Fig. 3 shows a section through the whole machine on line a: 90 of Fig. 1. Fig. 4 is a plan view partly broken away; Fig. 5, a detail in elevation of the safety or detent feed mechanism; Fig. 6, a plan detail of the sign-indicating board,pressing-lever,and theirimmediate connections; Fig. 7, a detail cross-section of the bar and its guide to which the pressing-lever is attached; Fig.8, a detail plan of the recessed spacing-plate, partly broken away, and its contact-bolt. Figs. 9 and 10 are respectively a side elevation and a sectional elevation of the spacing-leverssupporting post; Fig. 11, a perspective View in detail of the feed-pawl, and Fig. 12 a perspective detail of the section plate which carries the feed-pawl-supporting bolt and also the bolt which is pressed upon by the recessed spacing-plate.

The construction of the machine and its mode of operation is substantially as follows:

My invention relates to that class of ma chines wherein a vibratory lever is madeto traverse over a type-indicating board with its index to come opposite the sign or character to be printed, and the lever then pressed upon thus printing the respective correspondin g letter or sign character on the paper beneath, the return movement of the printinglever serving to effect thespacing to cause it to conform to the length of the type imprinted. The pressing-lever and imprinting mech- 3, which clearly upon which is "mounted two an le-frames a that form the main frame of the machine. These framepieces a carry at their free ends two plates b and b, hinged thereto at c (see Figs. 3 and 4,) the lower plate Z2 resting on the columns 0, the height of which maybe altered at will by means of the screws 0 attached to their ends. The springs 0 keep both plates 6 and b at a certain distance from each other. I) is fastened the sign-indicating board e by means of set screws cl, as represented clearly in Fig. 6, and also as partly broken away in Fig. 4, the said screws (1 at the same time serving as stay-bolts to hold the sign-indicating boards 6 and b at a certain distance from each other.

p The sign-indicating board 6 consists of a rectangular piece of sheet metal provided with a number of holes 6, underneath which the letters and combinations of letters, syllables, words, or sign-characters are arranged in rows in such manner that the rows marked I (see Fig. 6) contain only one letter or character, those marked II two letters, and finally those marked III three letters.

. Below the. sign-indicating board a a bar f carries lugs f,which support the pressing-leverf pivoted by bolt f thereon, said lever f being adapted to have its cide with the holes 6 of the indicating-board e. The bar f (shown in cross-section, Fig. 7) may be moved longitudinally on guide g, and as the said guide is fastened to the cross-bar g underneath the indicating-board e it may also be moved at right angles to the direction of its movement on guide g, so that this combination of movements permits the button f of the pressing-lever to be brought over any letter or sign of the sign-indicating board 6. The bar g is guided at its front edge by means of the turned-up edge 12 of the plate Z9 and at the rear edge by means of two small angleirons g screwed onto plate I).

On the plate button f coin- Bars h are suspended from both ends of the barf by means of pins h in such manner that the said bars h reach underneath the plate I) and support the frame 71 which carries the rubber type-plate h and carry the latter to coincide with the traverse of the pressing-lever f Above the type-plate b and on the under side of plate Z9 is arranged a stud i, which presses the type that happens to be underneath it through the hole 1" of the plate 1) against the paper sheet bybearing down upon the pressing-lever f.

The paper runs between the rubber rollers mounted on the carriage 70, then over the cross-bar k? and back, in the manner illustrated. The carriage is formed of the two exterior side plates It, which support the rollers 70, and are connected to each other by the bar 70 and the bolts I0 guide-bearing plates Z on bolts 70 serving to support and guide the carriage more truly and securely on the said guide-bar Z.

The spacing is accomplished by pressing down upon the lever f and concurrently upon the plate m, .Figs. 3, 4, and 6, which plate is connected by means of bolts with the cross-bar g, and is bent downwardly therefrom at a right angle to move a bolt 02 on the frame which carries the feed-pawl, the said plate m having, as illustrated in Fig. 8', three different recesses, viz., recess 1 pertaining to the rows I, recess 2 to rows II, and recess 3 to rows III, as will hereinafter appear.

In order to minimize the friction caused by pressing down upon the lever f and bring the plate on into contact with the bolt n, a hollow cylinder n is fitted over the bolt a to turn thereon and is held in position at one end by the regulating-nut n and at the other by the spring a The bolt or projects from an angle lever or sector 0, fulcrumed in 0 on the uprights o and guided by the screw 0 in the slit 0 as clearly shown by Fig. 12. I11 the upper end of the angle-lever 0 is screwed a horizontal bolt 19, which supports at its end the pawl 19 in position to engage with a rackbar 19 fastened to the guide-bearing plate Z of the carriage 70. When the lever f is pressed down, the plate m presses down the belt a, and thereby causes a movement of the angle-lever o, the pawl 13 slides over the teeth of the rack-bar p and on the return movement of the lever 0 displaces said rack-bar for a distance of as many teeth as it had traversed in the downward movement of said angle-lever. Thus when the plate m, with the projection 1, has its position above the bolt n, that is to say, when the pressing-lever f rests on a sign of the rows 1, the an gle-lever o is pressed down as far as required in order to let the pawl 19- pass over one tooth only. On the return of the angle-lever 0 a spacing is given equal to the pitch of the teeth of the rack-bar, that is, equal to the length of a type representing one letter. when the pressing lever f lies above a sign of the rows II, the plate at assumes its position with the projection 2 above the bolt a, the stroke of the angle-lever being then long enough to allow the pawl 19 to pass over two teeth of the rack-bar p whereby the paper-carriage is moved the length of two characters or letters. When finally the pressing-lever lies above a sign of the rows III, the plate m lies with its projection 3 above the bolt 01. The downward pressure of the an gle-lever will then be suflicient to cause the pawl 19 to pass over three teeth of the rack-bar 13*, whereby the paper-carriage is moved the length of three characters or letters. The backward movement of the an glelever 0 is caused by the spring q connecting said lever with a bracket-arm q, secured to the upright 0 of the frame.

The lever s, carrying the spacing-key s, rests upon the extension r of the bolt 01., and is pivoted at s on the column 0 and guided at its movable end in a slit in the post 8 and serves to operate the feed-pawl p, but its movement is only sufficient to allow the paper-carriage to be moved at each operation the distance of one letter or sign character.

A safety or detent feed mechanism (shown in Fig. 5) consists of a second rack-bar 15, which is attached to the rear end of the carriage k, and a pawl t, actuated by the bolt n or its projection 4" respectively and coincidently with the action of the actuating feecb pawl 0 upon the rack-bar 13 The pawl t is pivoted at t on the plate t and is pressed againstthe said rack-bar by the spring 15 and connected with the projection 'r by means of the loop 25 in such a mannerthat on the latter going downward the pawl t becomes disengaged from the said rack-bar i by the action of the parts 7", a, and 0, respectively, and also will rengage therewith when going back, thereby checking the backward movement of the carriage while the feed-pawl is moving backward upon its rack.

In order that the pawl 13 may be lifted from the rack-bar 19 and the carriage moved back by hand without obstruction, the bar a (shown in Fig. 2) is provided with a long slot to, which serves as, a guide for the finger a on the pawl 13, and the ends of said bar are bent upward at a and downward at w, and so supported on the carriage k that it may be pushed endwise by means, of the button u, and slide on said oblique surfaces a and a to thus raise and thereby disengage the pawl 9 from the rack-bar 19 so that the carriage 70, with its appliances, may he slid back to its initial point, and upon releasing said bar a, by removing the finger from the button a, the pawl will again engage with its rackbar ready for a forward movement of the carriage.

In order to have the type which corresponds with the position of the. pressing-button f appear properly above the stud t, the single type are so arranged on the rubber type-plate h that in a longitudinal as well as in an oblique direction they, the said signs on the typeplate, are arranged inversely to the sign letters or characters of the indicatingboard 6, the whole type-board being so far displaced in the backward direction that in its end position the foremost row'of types lies below the last row eating-board.

I claim as my invention and desire to secure by Letters Patent 1. A type-writin g machine such as described, comprising means for efiecting difierent lengths of spacingmovements of the papercarriage and consisting of a plate m, provided with a plurality of recesses and operatingfaces, the bolt n actuated by said plate, the angle-lever o, the pawl 12, connected there with, the rack-bar 12 the spring q for actuating the lever 0, the length of so many teeth moved by the paper-carriage being governed by the projecting faces of the said plate, substantially as described.

2. A type-writing machine such as described in combination with a movable paper-carriage, a pawl p connected therewith, a rackbar 19* connected with the frame of the maof signs of the indichine, a bar it having inclined ends a and a a supported in frame 70, and havinga slit to for guidance of the finger 1&2 connected with pawl 19 and for disengaging said pawl from the rack, substantially as described.
